SDSSJ133941.11+484727.5 : later stage of post-superoutburst superhumps?

 We have received further observations from Akazawa-san, Arto Oksanen.
According to these data, the amplitude of superhumps was small, ~ 0.15 
mag due to the beat phenomenon on March 17. Additionnaly, multiple peak
was also seen. Such peak had not been seen in the post-superoutburst.
As usual, such multiple peaks are seen in the later stage of the plateau.
J1339 also showed multiple peaks in the later stage of the plateau stage,
the profile had been clear single peaks again after the abrupt decline.
This multiple peak may also show the abrupt decline is approaching.

 Further observations are required!
